RESUMO
The estimated prevalence of the ectopic pregnancy (EP) is 1-2% of all pregnancies. Ovarian pregnancy is a rare finding with an incidence rate of 0.15% of all pregnancies and 1-3% of ectopic gestations. The use of intrauterine device (IUD) is a significant risk factor of ectopic pregnancy. Jaydess levonorgestrel intrauterine system (LNG-IUS) is considered as an extremely reliable method of contraception with the cumulative Pearl index of approx. 0.9% after a three-year period of use. This study presents a case of failure of the Jaydess intrauterine device in situ in a female patient with positive Beta Human Chorionic Gonadotropin (serum b-HCG) who was diagnosed with right-sided ovarian ectopic pregnancy. Although LNG-IUS represents the group of the most efficient contraception methods, the risks of failure still exist and should be taken into consideration. Before the insertion, every female patient should be fully informed on the potential adverse effects by a health practitioner.
